WebJan 7, 2024 · Margin Ranking Loss (nn.MarginRankingLoss) Margin Ranking Loss computes the criterion to predict the distances between inputs. This loss function is very different from others, like MSE or Cross-Entropy loss function. This function can calculate the loss provided there are inputs X1, X2, as well as a label tensor, y containing 1 or -1.

WebNov 25, 2024 · 2 Answers Sorted by: 7 If you know that for each example you only have 1 of 10 possible classes, you should be using CrossEntropyLoss, to which you pass your networks predictions, of shape [batch, n_classes], and labels of shape [batch] (each element of labels is an integer between 0 and n_classes-1 ). WebMargin ranking loss. Creates a criterion that measures the loss given inputs x 1, x 2, two 1D mini-batch Tensors , and a label 1D mini-batch tensor y (containing 1 or -1). If y = 1 then it assumed the first input should be ranked higher (have a larger value) than the second input, and vice-versa for y = − 1.
